NAME

       sd-journal - APIs for submitting and querying log entries to and from the journal

SYNOPSIS

       #include <systemd/sd-journal.h>

       pkg-config --cflags --libs libsystemd-journal

DESCRIPTION

       sd-journal.h provides APIs to submit and query log entries. The APIs exposed act both as
       client for the systemd-journald.service(8) journal service and as parser for the journal
       files on disk.

       See sd_journal_print(3), sd_journal_stream_fd(3), sd_journal_open(3), sd_journal_next(3),
       sd_journal_get_realtime_usec(3), sd_journal_add_match(3), sd_journal_seek_head(3),
       sd_journal_get_cursor(3), sd_journal_cutoff_realtime_usec(3), sd_journal_get_usage(3),
       sd_journal_get_catalog(3) and sd_journal_get_fd(3) for more information about the
       functions implemented.

       Command line access for submitting entries to the journal is available with the systemd-
       cat(1) tool. Command line access for querying entries from the journal is available with
       the journalctl(1) tool.

NOTES

       These APIs are implemented as shared library, which can be compiled and linked to with the
       libsystemd-journalpkg-config(1) file.
